The Austrian-born model started strutting the runway at the tender of age of 13, taking part in shows like Germany’s Next Top Model as well as making it to the finals of Elite Model Look.

The 19-year-old told Metro that and as she grew older she started realizing the dark truth behind the sought after fashion industry and she wants to tell people about the ‘behind-the scenes’ and the ‘pressure to be underweight’ truths of modelling.

“I tried to think of ways to change it and I think you can only change a system if you’re part of it. So I knew I had to become someone in the industry before people would start to listen to what I have to say,”

“I get so many messages from young people who ask me how they can lose weight or other beauty questions.

“I never give them advice, I only ask them: “If you were the only person on this planet and no one could see you, would you still want to change your body?”‘

As a way to pave a positive way for many young girls who want to be in the modelling industry, Jazz started using the candid hashtag #truthbehindthisshot to unearth all her struggles in the glitzy and glamorous modelling world.

Jazz’s Instagram feed is filled with raw and honest captions behind what happened while the pictures were taken, taking aim at ‘miserable stylists and revealing that most of her high-end pictures are in fact highly edited and most of her poses are ‘rehearsed’ “to make certain parts of her body slimmer.”

Jazz is a UK size 6 and while she is not as confident about her body yet, she hopes her 18 000 followers will gain confidence and spread positive images of their bodies.

“That's one big issue. I think, if more designers created standard sizes, the pressure to be underweight would decrease. But that's one issue in a million. There are tons of reasons why the industry needs a revolution. Promoting a healthy body image is so important.”

Sadly, Jazz told Metro that she doesn’t enjoy posting her pictures on the photo sharing app, but she is forced to do so to build her modelling profile.
